About Devialet
Founded in Paris in 2007, Devialet is a French audio technology company distinguished by its proprietary acoustic engineering and sculptural product design. Renowned for its Phantom speakers and Expert amplifiers, the brand brings together scientific research, technological innovation and a refined approach to listening. As an employer, its activities span engineering, industrial design, software development, manufacturing, marketing and retail, connecting technical expertise with the expectations of a discerning international clientele. Devialet represents a distinctive career setting for professionals drawn to the intersection of sound, design and premium consumer technology, with acoustic performance at the heart of its identity.
The entry-level Embedded Audio Integration Engineer joins Devialet’s DSP & Acoustics team, based in La Défense, and works with Signal Processing, Acoustics and Software teams to integrate and optimize proprietary audio algorithms on real-time embedded targets. The role spans technical scoping and presales through development, validation, industrialization and client and partner support; it is a permanent CDI contract, with occasional remote work and rare travel.
Role & Responsibilities
- Maintain and evolve Devialet’s embedded audio library.
- Deliver library releases and support integration for licensing clients and partners; internal projects may be considered in the future.
- Implement complete processing chains using the internal algorithm library and port updates and new algorithms developed by the Signal Processing team.
- Design, specify and document the public C API, including versioning and compatibility between versions.
- Build libraries for each target using the relevant toolchain, including CrossCore Embedded Studio and ARM toolchains.
- Industrialize deliverables, including headers, binaries and documentation, to support several concurrent projects.
- Contribute to technical scoping and presales, including MCPS and memory estimates, then support client integration and debugging.
- Define and apply measurement protocols for MCPS, memory and latency, covering worst-case and average results with explicit measurement conditions.
- Measure, characterize and document the processing chain’s latency for clients.
- Balance the needs of external clients with those of internal products.
- Create C audio pipelines by assembling reusable generic components in an existing audio framework.
- Contribute to defining components, including input and output formats, lifecycle, parameters, and declared MCPS, memory and latency costs.
- Evolve existing modules from supplied Matlab/Simulink or MaxMSP reference models, port them to embedded float32 C and validate them.
- Optimize code for each target using portable C and target-specific optimizations, including intrinsics, SIMD and CMSIS-DSP.
- Validate target outputs against Matlab/Simulink or MaxMSP reference models using test vectors, and analyze and diagnose discrepancies.
- Maintain and improve the Jenkins CI pipeline for automated builds and tests on PC and target hardware.
- Contribute to developing and maintaining the team’s Python tools.
Qualifications
- Engineering degree or Master’s in embedded systems, or equivalent.
- Strong command of real-time embedded C, including reading and maintaining existing code.
- Experience designing C APIs and architectures for reusable components.
- Python, including extensions and interoperability with C.
- Experience measuring MCPS and memory on target hardware.
- Experience porting and optimizing audio algorithms in C.
- Matlab is appreciated for reading reference models and analyzing discrepancies.
- Testing and CI mindset.
- Fluent spoken and written English.
- Analytical thinking, rigour and autonomy.
- Ease working with internal technical teams and external clients.
- A preference for integration, client support and software quality over algorithmic research.
- Strong interest in audio and high-end embedded technologies.
- Required targets and toolchains: SHARC (Analog Devices), ARM Linux, and Cadence HiFi 4 and/or HiFi 5.
- Highly appreciated: STM and GigaDevice (MCU).
- A plus: Qualcomm DSP solutions.
- Occasional travel may be required.
